ext4: fix null pointer dereference on sbi
In the case of a kzalloc failure when allocating sbi we end up
with a null pointer dereference on sbi when assigning sbi->s_daxdev.
Fix this by moving the assignment of sbi->s_daxdev to after the
null pointer check of sbi.
Detected by CoverityScan CID#1455379 ("Dereference before null check")
Fixes: 5e405595e5bf ("ext4: perform dax_device lookup at mount")
